ImPPG Image Post Processing Software

ImPPG Image Post Processing Software is an astronomy image post processoring program that performs Lucy-Richardson deconvolution, unsharp masking, brightness normalization and tone curve adjustment. It can also apply previously specified processing settings to multiple images. All operations are performed using 32-bitfloating-point arithmetic.

ImPPG Image Post Processing SoftwareA new version of the software has recently been released with new features including improving combinations of system language and regional settings. ImPPG Supports input the following formats: FITS, BMP, JPEG, PNG, TIFF (most of bit depths and compression methods), TGA and more. Images are processed in grayscale and can be saved as: BMP 8-bit; PNG 8-bit; TIFF 8-bit, 16-bit, 32-bit floating-point (no compression, LZW- or ZIP-compressed), FITS 8-bit, 16-bit, 32-bit floating-point.

ImPPG Image Post Processing Software can also align an image sequence, with possibly large and chaotic translations between images (aligned output images preserve number of channels and bit depth). This can be useful, for example, when preparing a solar time-lapse animation, where subsequent frames are offset due to inaccurate tracking of the telescope mount. Other possible applications are smoothing out of terrestrial landscape time-lapses or preparing raw frames (with serious image jitter) for stacking.

ImPPG is free and open-source, licensed under GNU GPL v3 (or later). Building from source code (C++) requires Boost, wxWidgets and (optionally) FreeImage & CFITSIO libraries and is possible on multiple platforms. Windows executables (32- and 64-bit) can be downloaded using the links below. See the README file for details on usage and building.
